1 Solution Overview

The backup storage solution provides a backup system with software and hardware deployed independently. It includes the backup software, backup agent, backup management server, backup storage server, and backup storage. Figure 1-1 shows the solution architecture.

Figure 1-1 Backup storage solution architecture

Solution Components

  • Mainstream backup software, including NetWorker, Veritas NetBackup, Veeam, Commvault, and IBM Spectrum Protect.
  • Backup management server: manages components in the backup system. It is used to create, execute, and schedule backup jobs and configure backup policies. It can be deployed independently or together with the media server.
  • Backup agent client: It is installed on protected application production servers and VMs, responds to backup job scheduling by the backup management server, collects and manages data to be protected, and transmits the data to the backup storage server.
  • Backup storage server (also called media server): It is deployed independently and responds to job scheduling by the backup management server. It processes backup data flows and manages backup data transmission and storage devices. Some vendors provide backup data deduplication and compression on the backup storage server.
  • Backup storage: It is connected to the backup storage server and used to receive and store backup data. Some backup storage devices provide deduplication and compression. Based on service requirements, there are tier-1 backup storage and tier-2 backup storage. Tier-1 backup storage provides rapid and efficient backup and restoration with optimal performance. As tier-1 backup storage is expensive, deduplication and compression are important. Tier-2 backup storage provides long-term retention (LTR) at a low cost. Backup copies before a certain point in time can be migrated to tier-2 backup storage for an optimal comprehensive retention cost. Common backup storage types include backup storage, general-purpose storage, virtual tape library (VTL), object storage, and tape library.

Solution Description

  • During backup, the backup management server delivers a backup scheduling command to the backup agent. Then, the backup agent collects and transmits data based on the set backup policy. The backup storage server processes the data transmitted by the backup agent, writes the data to the backup storage in a certain format, and records indexes.
  • Performance of a single backup storage server is limited. Backup storage server scale-out is supported for performance improvement.
  • Backup data replication: Remote backup data DR is required to meet compliance and data security requirements. Data can be replicated and transmitted through the backup storage server or tier-1 backup device.
  • Backup data long-term retention (LTR): LTR solutions apply to scenarios where backup copies need to be retained for a long time with rapid restoration available. Based on policies, latest copies are stored on tier-1 backup media with rapid backup, access, and restoration supported. Copies that need to be retained for a long time are stored on tier-2 backup media with lower costs. In this way, the overall retention cost is optimal.

This document describes the backup storage solution based on the OceanProtect backup storage integrating IBM Spectrum Protect.

2 Solution Introduction

The backup storage solution based on Huawei OceanProtect backup storage integrating IBM Spectrum Protect can be used to back up application systems, replicate backup copies, and implement LTR-based tiering.

2.1 Solution Components

2.1.1 IBM Spectrum Protect Backup Software

Spectrum Protect is a data protection platform that provides unified control and management for enterprises and supports backup and restoration for virtual, physical, and cloud environments at all scales.

The basic architecture of Spectrum Protect is as follows.

The data protection solution provided by IBM Spectrum Protect includes servers, client systems and applications, and storage media. Spectrum Protect provides a management interface for monitoring and reporting data protection status.

  • Server

Client systems send data to the server to be stored as backups or archived data. The server includes an inventory, which is a repository of information about client data.

The inventory includes the following components:

  • Database

Information about each file, logical volume, or database that the server archives, migrates or creates a backup of, is stored in the server database. The server database also contains information about the policy and schedules for data protection services.

  • Recovery log

Records of database transactions are kept in this log. The recovery log helps to maintain data consistency in the database.

  • Client systems and applications

Clients are applications, VMs, and systems that must be protected. The clients send data to the server.

  • Client software

For IBM Spectrum Protect to protect client data, the appropriate software must be installed on the client system and the client must be registered with the server.

  • Client nodes

A client node is equivalent to a computer, a VM, or an application, such as a backup-archive client that is installed on a workstation for file system backups. Each client node must be registered with the server. Multiple nodes can be registered on a single computer.

  • Storage media

The server stores client data to storage media. The following types of media are used:

  • Storage devices

The server can write data to hard disk drives, disk arrays and subsystems, stand-alone tape drives, tape libraries, and other types of random-access and sequential-access storage. Storage devices can be connected directly to the server or connected through a local area network (LAN) or a storage area network (SAN).

  • Storage pools

Storage devices that are connected to the server are grouped into storage pools. Each storage pool represents a set of storage devices of the same media type, such as disk or tape drives. IBM Spectrum Protect stores all of the client data in storage pools. You can organize storage pools into a hierarchy, so that data storage can be transferred from disk storage to lower-cost storage such as tape devices.

Functions of Spectrum Protect

Spectrum Protect uses policies to control how the server stores and manages data objects on various types of storage devices and media. You associate a client with a policy domain that contains one active policy set. When a client backs up, archives, or migrates a file, the file is bound to a management class in the active policy set of the policy domain. The management class and the backup and archive copy groups specify where files are stored and how they are managed. If you set up server storage in a hierarchy, you can migrate files to different storage pools.

Spectrum Protect provides the following data protection services:

  • Backup and restoration services: Run a backup process to create a copy of a data object that can be used for restoration if the original data object is lost.
  • Archive and retrieve services: Use the archive service to preserve data that must be stored for a long time, or use the retrieve service to replicate data from the storage pool to the client node for regulatory compliance or other purposes.
  • Migration and recall services: You use migration and recall services to manage space on client systems. The goal of space management is to maximize available media capacity for new data and to minimize access time to data.

2.1.2 OceanProtect Backup Storage

Product Positioning

As the amount, types, and growth rate of data change exponentially, enterprises face increasing data loss risks due to human errors, viruses, natural disasters, and Cyber resilience threats. Therefore, data protection becomes increasingly important.

OceanProtect backup storage features rapid backup, rapid restoration, efficient reduction, and solid resilience. It implements efficient backup and restoration with the TCO greatly reduced. It is widely used in government, finance, carrier, healthcare, and manufacturing industries. In addition, it offers easy management and convenient local/remote maintenance, significantly reducing device management and maintenance costs.

OceanProtect backup storage is available in all-flash and hard disk drive (HDD) forms.

  • All-flash form: The system supports only SSDs. Service data and metadata are stored on SSDs.
  • HDD form: The system supports SSDs and HDDs. Service data is stored on a storage pool composed of HDDs. SSDs only store system metadata. SSDs delivering higher performance accelerate metadata access, improving read and write performance.

Product Highlights

With the active-active high-reliability architecture and full-process acceleration, OceanProtect backup storage features rapid backup, rapid restoration, efficient reduction, and solid resilience.

In addition, OceanProtect 1.2.0 provides source deduplication and deduplicated replication to effectively save the logical bandwidth and decrease network resource occupation.

  • Rapid backup and restoration
  • Full-process acceleration is implemented. The front-end network protocol offload technology reduces the CPU pressure, and back-end CPU multi-core parallel scheduling is implemented. Dedicated cores are used based on grouping and task partitioning, efficiently improving the processing capability of nodes.
  • Based on backup service characteristics, multiple sequential data flows are aggregated for read and write, greatly improving bandwidth performance. Source deduplication reduces the amount of data to be transmitted over the network, shortening the backup duration.
  • The system provides high IOPS performance and can work with mainstream backup software. Backup image data can be accessed instantly, enabling fast utilization of backup data.
  • Efficient reduction
  • Accurate backup data segmentation, backup data aggregation preprocessing, and multi-layer inline variable-length deduplication are used to increase the logical capacity and reduce the total cost of operations (TCO).
  • Data flow features can be identified. Combination-based compression, high-performance predictive encoding, and byte-level compaction are used to improve the data reduction ratio.
  • Source deduplication and deduplicated replication are used to reduce network bandwidth costs.
  • Solid resilience
  • The active-active redundant hardware architecture design ensures that ongoing backup jobs, if a controller is faulty, can be switched over in seconds without being interrupted.
  • Protocol encryption, replication link encryption, array encryption, secure snapshots, and write once read many (WORM) are used to ensure security and availability of copies.

2.2 Solution Architecture

2.2.1 Overall Solution Architecture

Figure 2-1 Overall architecture of the OceanProtect backup storage + IBM Spectrum Protect

Solution overview:

  1. Backup and recovery
  • OceanProtect supports multiple protocols: DataTurbo (IP), DataTurbo (Fibre Channel), standard NFS/CIFS, and SAN.
  • IBM Spectrum Protect supports the following types of storage pools as backup media: directory-container storage pool, cloud-container storage pool, random-access storage pool, and sequential-access storage pool (including DISK and FILE device types).
  • It is recommended that you configure the OceanProtect file systems as the sequential-access storage pool of the FILE device type. Alternatively, use the directory-container storage pool. DataTurbo of OceanProtect is recommended for the interconnection.
  1. Remote replication

When IBM Spectrum Protect uses replication of the backup storage, the replicated data can only be used for disaster recovery (DR).

This replication solution is for DR scenarios. When the secondary backup server is in the standby state, only the database and backup data is used for recovery

  1. LTR copy tiering

Tiering rules are configured in IBM storage rules. Tiering can be performed only for directory-container storage pools. The target storage pools must be cloud-container storage pools or tape devices.

2.2.2 Backup Solution Architecture

Figure 2-2 Backup solution architecture

Solution overview:

  1. Backup components
  • Backup server: The backup system uses a two-layer architecture. The server integrates the management server and media server and has a built-in DB2 database for configuration, information recording, and metadata management. The Server supports AIX, Linux, and Windows.
  • Backup client: It is installed on the production server and must be registered with the backup server to respond to the scheduling commands of the server and collect and transmit data.
  • Storage media: OceanProtect is recommended.
  1. Protocol
  • OceanProtect supports multiple protocols: DataTurbo IP, DataTurbo Fibre Channel, standard NFS/CIFS, and SAN.
  • IBM Spectrum Protect supports five types of storage pools as backup media. The sequential-access storage pool of the FILE device type is recommended.

IBM Spectrum Protect deduplication is enabled by default for directory-container storage pools and cannot be disabled, affecting the OceanProtect deduplication and compression ratio. Therefore, the directory-container storage pool is the secondary candidate storage pool.

  1. Deduplication and compression

OceanProtect deduplication and compression are recommended. DataTurbo source deduplication is preferred.

2.2.3 Replication Solution Architecture

Figure 2-3 Replication solution architecture

Solution overview:

  1. Remote replication using OceanProtect

Remotely replicating backup copies from the production data center (DC) to the DR DC for storage is the process of remotely reconstructing a server in the Tivoli Storage Manager (TSM) backup solution. The deduplicated replication function of OceanProtect is used to implement efficient copy replication.

  1. Replication mode

Supports one-to-one, one-to-many, and many-to-one replication.

  1. Replication description

Only DR-level replication is supported. The procedure is as follows:

  1. Use deduplicated replication of OceanProtect to replicate backup copies, which transmits only deduplicated data to save network bandwidth.
  2. The backup configurations and metadata are stored in the DB2 database of the server. The DB2 database is backed up locally to the file systems of OceanProtect. The local OceanProtect performs deduplicated replication to replicate the DB2 backup copies to OceanProtect of DC2.
  3. During recovery, the DB2 copies in DC2 are used to recover the task configurations and metadata in the server.

This replication solution is for DR scenarios. When the secondary backup server is in the standby state, only the database metadata and backup data are imported for recovery.

2.2.4 Tiering Solution Architecture

Tiering solution architecture

Solution overview:

IBM Spectrum Protect supports tiering to object storage or cloud storage.

In this solution, you are advised to use the tiering function of IBM Spectrum Protect, which supports tiering only from directory-container storage pools. The target storage can be tape libraries, S3 object storage, and public cloud storage.

  • IBM Spectrum Protect backs up application data to the OceanProtect backup storage for short-term retention.
  • In the IBM Spectrum Protect storage rules, configure tiering rules and set the source storage pool (directory-container storage pool only) and target storage pool (tape device or cloud-container storage pool).

Configure a tiering policy. For example, tiering is triggered at XX:YY every day to tier copies that have been stored for more than X days. Backup copies are tiered to the OceanStor Pacific object storage based on the tiering policy.

  • On the IBM Spectrum Protect GUI, you can directly use a tiered copy on OceanStor Pacific for restoration.
  • Only copies in directory-container storage pools can be tiered.
  • Deduplication by the backup software is enabled by default for directory-container storage pools and cannot be disabled.

3 Planning Suggestions

3.1 Network Planning for Different OceanProtect Models

In OceanProtect 1.3.0, the customer can select OceanProtect X3000, X6000, X8000, and X9000 based on different backup capacity and performance requirements. The networking configuration principles of all models must comply with the principles described in 4.3 Configuration Planning for IBM Spectrum Protect Integration.

3.2 Backup Capacity and Performance Planning

  • Backup capacity calculation

The OceanProtect capacity is planned based on the backup data capacity and copy retention policy. In this best practice, 25 SSDs (3.84 TB each) are configured for OceanProtect X8000.

  • Backup performance calculation

The backup performance of the backup system is planned based on the backup window, backup copy capacity, and OceanProtect configuration. In this best practice, the backup performance of a single IBM Spectrum Protect server is 2 GB/s.

3.3 OceanProtect X8000 Configuration Planning

Storage Resource Planning

  • Disk type planning: Storage pools can be created using SSDs and HDDs. Table 3-1 describes disk type planning.

A storage pool contains SSDs and HDDs.

Disk Quantity
  • In all-flash form, storage pools support only SSDs. Data and metadata are stored on SSDs.
  • At least eight SSDs are required.
  • At least six SSDs (cache disks) and eight HDDs (data disks) are required for each controller enclosure.
  • Capacity of SSDs (cache disks) must be greater than or equal to 5% of capacity of HDDs (data disks).
  • Storage capacity planning: Generally, capacity of OceanProtect X8000 is planned based on the backup data capacity and retention period.
  • Compression mode planning: Storage pools support high reduction ratio (default) and high performance compression modes.

The high reduction ratio mode delivers higher reduction ratio than the high performance mode.

  • Storage pool planning: A storage pool is a container that stores resources. It provides storage space for all application servers. For core services, RAID-TP is recommended. Table 3-2 describes storage pool protection levels.

Description

Capacity

File system capacity is planned based on service requirements.

Quantity

To ensure performance, it is recommended that four file systems be configured.

Application type
  • The file system application type can be Reduction_Prioritized_Mode_enhanced (default value) or Performance_Prioritized_Mode_enhanced.
  • By default, Reduction_Prioritized_Mode_enhanced is recommended for the file system application type, and the high reduction ratio mode is recommended for the storage pool compression mode.
  • If there are high requirements on the backup time window and backup bandwidth, it is recommended that the file system application type be set to Performance_Prioritized_Mode_enhanced and the storage pool compression mode be set to high performance mode.
  • File system sharing: OceanProtect X8000 provides CIFS, NFS, and DataTurbo shares. Source deduplication is planned in this solution. Currently, DataTurbo shares support TCP or Fibre Channel networks. Therefore, select the DataTurbo share for file system sharing. For details about OS and backup software versions supported by the DataTurbo client, visit the compatibility website.

Compatibility query website: https://info.support.huawei.com/storage/comp/#/oceanprotect

TCP Network Planning

  • Physical port planning
  • Quantity planning: After source deduplication is enabled, the required physical bandwidth can be planned based on the number of backup hosts. Two 10GE ports for each backup host can meet the bandwidth requirements. For example, if there are four backup hosts, eight physical ports are required for the back-end OceanProtect X8000.
  • Configuration planning: OceanProtect X8000 is a dual-controller device. To ensure reliability, the planned network interface cards (NICs) must be evenly distributed to controllers A and B.
  • Logical port planning
  • Quantity planning: Logical ports are created for running NAS services. You are advised to configure at least one logical port for each physical port.
  • Configuration planning: An OceanProtect X8000 device has two controllers (A and B). It is recommended that 2 x 10GE of a backup host be connected to the logical ports of controllers A and B on OceanProtect X8000, respectively.

Fibre Channel Network Planning

  • Physical port planning
  • Quantity planning: After source deduplication is enabled, the required physical bandwidth can be planned based on the number of backup hosts. Two 16 Gbit/s ports for each backup host can meet the bandwidth requirements. For example, if there are four backup hosts, eight physical ports are required for the back-end OceanProtect X8000.
  • Configuration planning: OceanProtect X8000 is a dual-controller device. To ensure reliability, the planned NICs must be evenly distributed to controllers A and B.

3.4 IBM Spectrum Protect Planning

This solution adopts the source deduplication feature and uses the DataTurbo protocol for integration with OceanProtect X8000. Both IBM Spectrum Protect and OceanStor DataTurbo need to be deployed on the IBM Spectrum Protect servers.

  • Server requirements: Plan the number of servers based on the required backup network bandwidth. For details about DataTurbo’s requirements on servers, see « Backup Server Requirements » in the OceanProtect Backup Storage 1.3.0 SourceDedupe User Guide.
  • OS requirements: For details about the OS requirements of IBM Spectrum Protect, see IBM Spectrum Protect official documents. The OceanStor DataTurbo software must be deployed on the IBM Spectrum Protect servers and meet the compatibility requirements. For details, visit the compatibility query website: https://info.support.huawei.com/storage/comp/#/oceanprotect.
  • NIC requirements: The IBM Spectrum Protect server is connected to both the production system and the backup storage device. Both the front-end and back-end NICs must meet the backup bandwidth requirements to avoid bottlenecks.
  • Front-end network: It’s used to establish connections with the production environment. Therefore, the backup capability of each IBM Spectrum Protect server must be achieved to prevent the front-end network configuration from becoming a bottleneck. In this solution, the capability of a single IBM Spectrum Protect server is evaluated as 5 GB/s, and the front-end network is deployed with 4 x 10GE, which can be adjusted based on the MA capability in actual tests.
  • Back-end TCP network: This solution uses the source deduplication feature. Therefore, the back-end network of the IBM Spectrum Protect server does not need to have the same configuration as the front-end network. You are advised to deploy 2 x 10GE for each IBM Spectrum Protect server to connect to controllers A and B of OceanProtect X8000, respectively.
  • Back-end Fibre Channel network: This solution uses the source deduplication feature. Therefore, the back-end network of the IBM Spectrum Protect server does not need to have the same configuration as the front-end network. You are advised to deploy 2 x 16 Gbit/s links for each IBM Spectrum Protect server to connect to controllers A and B of OceanProtect X8000, respectively.

To achieve a good deduplication effect, you are advised to disable the deduplication and compression functions of backup software and disable the compression and encryption functions of applications to be backed up. For example, disable compression and encryption of Oracle RMAN.

4.3 Configuration Planning for IBM Spectrum Protect Integration

  • Storage pool on OceanProtect X8000: Create a storage pool, configure 25 x 3.492 TB SAS SSDs, and set the RAID policy to RAID 6.
  • File systems of OceanProtect X8000: Take two IBM Spectrum Protect servers as an example. Plan two file systems for the two controllers (one for each controller) and 100 TB logical capacity for each file system.
  • Logical ports on OceanProtect X8000: OceanProtect X8000 is connected to the two front-end IBM Spectrum Protect servers through 4 x 10GE physical links. Each physical port is configured with one logical port.
  • Storage pool planning:
  • On OceanProtect X8000, create two file systems that are owned by controllers A and B, respectively, and mount each file system to a backup server.
  • One file system is mounted to each IBM Spectrum Protect server, and one storage pool is created for the file system.

Figure 4-3 shows the mounting details.

Mounting file systems

Backup principle: Periodic backup copy data of the same type of applications is written to the same deduplication domain.

Networking principles:

  • It is recommended that one storage pool be planned for a type of applications. The mapping relationship between storage pools and file systems is one-to-one and that between storage pools and backup media servers is also one-to-one.
  • To maximize the performance of X9000 HDD, 16 file systems are required.

4.4.3 Installing and Configuring IBM Spectrum Protect

The IBM Spectrum Protect 8.1.13 software is used in this backup solution. For details about how to install and configure IBM Spectrum Protect (servers and clients), see its official documents.

4.4.4 Configuring Source Deduplication

This solution uses source deduplication, which requires the DataTurbo protocol for interconnecting with the IBM Spectrum Protect server. DataTurbo shares are created on OceanProtect X8000. To mount the corresponding file systems to the backup hosts using the DataTurbo protocol, you need to install the OceanStor DataTurbo software and configure related parameters on media servers.

This section describes how to configure source deduplication. In addition, IBM Spectrum Protect servers and OceanProtect X8000 can mount file systems using the NFS protocol. If the NFS protocol is used, it is recommended that the NFS 3.0 protocol and synchronous soft mounting mode be used to mount the file systems. Set the retry waiting time and number of retries of the NFS client. Run the mount -t nfs -o sync,vers=3,soft,timeo=10,retrans=2 source target command to mount file systems.

  • source: The format is IP:/file name, where IP and file name indicate the logical port IP address and file system name of OceanProtect X8000, respectively.
  • target: indicates the directory created on the IBM Spectrum Protect server for mounting the file system, for example, /home/data1.

4.4.4.1 Installation and Deployment

OceanStor DataTurbo must be installed on all backup hosts. For details about how to install OceanStor DataTurbo, see « Installation, Upgrade, and Uninstallation » in the OceanProtect Backup Storage 1.3.0 SourceDedupe User Guide. During the installation, set the performance level to high.

4.4.4.2 Parameter Configuration

The DataTurbo configuration consists of two parts: establishing connections and mounting file systems.

  • Connection establishment: Establish physical links between two ports of each IBM Spectrum Protect server and controllers A and B of OceanProtect X8000, respectively. That is, each backup host is connected to the back-end storage through two links.
  • File system mounting: Create two file systems on the OceanProtect X8000 and mount them to two IBM Spectrum Protect servers.

Establishing TCP Links

Step 1 Run the dataturbo create storage_object storage_name=name ip_list=IP address command (name indicates the user-defined storage name, and IP address indicates the IP address of the logical port created on OceanProtect X8000) to establish connection between OceanStor DataTurbo and OceanProtect X8000. Enter the username and password of the created DataTurbo user as prompted.

In this example, the storage name is storage1 and the logical port IP address is 10.10.10.10.

[root@host192 mnt]# dataturbo create storage_object storage_name=storage1 ip_list=10.10.10.10
Please input username:
DataTurbo_user
Please input password:
**********
Create storage object successfully.

Step 2 Run the dataturbo show storage_object command to check whether the connection is successfully established.

If the following information is displayed and Status is Normal, the connection is successfully established.

[root@host192 mnt]# dataturbo show storage_object
Storage Name: huawei
User : DataTurbo_user
Ips : 10.10.10.10
IpPair :
ID Local Address Remote Address Status
—————————————————————
1 10.10.10.101 10.10.10.10 Normal

Step 3 After the connection is established, log in to DeviceManager and choose Services > DataTurbo Clients to view the backup server information.

—-End

Establishing Fibre Channel Links

Step 1 Run the dataturbo_rescan command to detect the change of the channel LUN mappings created in 4.4.2.5 Creating Channel LUNs and Mappings (Fibre Channel Networking).

In the following example, delete sg xxxx indicates that the channel LUN mapping is removed, and scan hostx indicates that the channel LUN mapping is added.

[root@localhost ~]# dataturbo_rescan
delete sg device sg2 sucess.
delete sg device sg3 sucess.
scan host1
scan host2

Step 2 Run the dataturbo create storage_object storage_name=name link_type=FC command (name indicates the user-defined storage name) to establish connection between the DataTurbo client and backup storage system.

Enter the username and password of the created DataTurbo user as prompted. If Create storage object successfully is displayed as shown in this example, the storage object is successfully created.

[root@localhost ~]# dataturbo create storage_object storage_name=test123 link_type=FC
Please input username:
test_001
Please input password:
**********
Create storage object successfully.

Step 3 Run the dataturbo show storage_object command to check whether the connection is successfully established.

In the following example, four Fibre Channel links are created on the backup storage. If Status is Normal, the connections are successful and the links are normal.

[root@localhost ~]# dataturbo show storage_object
Storage Name: test123
User : test_001
ID Initiator WWN Target WWN Status
—————————————————————
1 210000********c4 2800**********58 Normal
2 210000********c4 2801**********58 Normal
3 210000********c4 28b0**********3d Normal
4 210000********c4 28e0**********58 Normal

—-End

Mounting File Systems

Step 1 Run the dataturbo mount storage_object storage_name=name filesystem_name=/fsname mount_dir=/mnt/test command to mount a file system created on the backup storage to a specified mount point.

name indicates the storage name defined during the TCP/Fibre Channel link establishment. fsname indicates the name of the file system created in 4.4.2.6 Creating File Systems and Shares.

In the following example, the storage name is storage1, the file system name is testfile, and the mount point is /mnt/test.

[root@host192 mnt]# dataturbo mount storage_object storage_name=storage1 filesystem_name=/testfile mount_dir=/mnt/test
Command executed successfully.

Step 2 Run the df -h command to check whether the mounting is successful.

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/centos-root 45G 24G 21G 55% /
devtmpfs 4.8G 0 4.8G 0% /dev
tmpfs 4.9G 8.0K 4.9G 1% /dev/shm
tmpfs 4.9G 9.3M 4.8G 1% /run
tmpfs 4.9G 0 4.9G 0% /sys/fs/cgroup
